Happy days die...but some survive

I got a call some hours ago. My brother was on the phone and he sounded desperate: "Come here, fast! Something's wrong with mum". He told me, he found mum lying on the floor, without any signs of life.
So I drove to my mums house. When I came in, I saw my mum on the couch (fortunately awake) and she looked around the room. I do not know, if she noticed me. I said some words to her, but she just looked through me and gave some weird and contextless answers. So my dad hug her, let her cry on his shoulder and spoke to her. I went with my brother in his room and talked.
He told me, that my mum swallowed too many sleeping pills. She told him, she just took one, but we don't believe it. Now we are worried.
Sure, my relationship and my time with her was hard..but I think. There's not only hate inside of me. Because today I thought for a short moment I would lose her and it hurts. Maybe I still love her... a little bit...deep inside of me. Because, if I'm not, why am I so worried?
My brother and me don't know, if she really wanted to lay hands upon herself, but we do not expect it.
I've never seen my mum like this before. So..so... I don't know how to express it, but it was horrible. Depressing. Sad.
How will life go on? We do not know. We just know, that it will go on...somehow.
